New method to induce protein folding

A new method to induce protein folding by taking the pressure off of proteins is up to 100 times faster than previous methods, and could help guide more accurate computer simulations for how complex proteins fold, according to research by a team of University of Illinois scientists accepted for publication in the journal Nature Methods and posted on the journal's Web site May 31.

Oligophrenin-1 signaling protein linked to mental retardation controls synapse maturation, plasticity

A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate.

Lower levels of PHD2 protein influence tumor growth in mice

Tumors need a healthy supply of blood to grow and spread. Researchers at the Stanford University School of Medicine have identified a molecule that regulates blood vessel growth that is often found at less-than-normal levels in human tumors. Blocking the expression of the molecule, called PHD2, allows human cancer cells to grow more quickly when implanted into mice and increases the number of blood vessels feeding the tumor.

Old drug Auranofin may lead to new antibiotics

A mineral found at health food stores could be the key to developing a new line of antibiotics for bacteria that commonly cause diarrhea, tooth decay and, in some severe cases, death.

New credit card-sized device detects heart disease using less than one drop of blood

Testing people for heart disease might be just a finger prick away thanks to a new credit card-sized device created by a team of researchers from Harvard and Northeastern universities in Boston.

“Misreading” of histone code linked to human cancer

The development of blood from stem cell to fully formed blood cell follows a genetically determined program. When it works properly, blood formation stops when it reaches maturity. But when it doesn't, genetic mutations can prevent the stop signal and cause the developing cells to turn cancerous. In research published in Nature, Rockefeller University scientists show for the first time that a misreading of the blood cells' histone code is responsible for acute myeloid leukemia, a rare form of the deadly blood cancer.

Experts say let swine flu run its course

With the number of influenza A H1N1 (swine flu) cases in Australia now over 300 federal Health Minister Nicola Roxon says the government is considering whether to elevate the nation's response to the disease from the contain to sustain phase, as it may be impossible to keep quarantining people.

Sleep disordered breathing in children in a general population sample: prevalence and risk factors

A study in the June 1 issue of the journal SLEEP found that waist circumference and body mass index (BMI) are consistent, independent risk factors for all severity levels of sleep disordered breathing (SDB) in children, suggesting that as with adult SDB, metabolic factors are important risk factors for childhood SDB.

Research links intestinal inflammation with systemic chromosome damage

UCLA scientists have linked for the first time intestinal inflammation with systemic chromosome damage in mice, a finding that may lead to the early identification and treatment of human inflammatory disorders, some of which increase risk for several types of cancer.

Combination of gene therapy and induced pluripotent stem cells cure human genetic disease in vitro

A study led by researchers at the Salk Institute for Biological Studies, has catapulted the field of regenerative medicine significantly forward, proving in principle that a human genetic disease can be cured using a combination of gene therapy and induced pluripotent stem (iPS) cell technology. The study, published in the May 31, 2009 early online edition of Nature, is a major milestone on the path from the laboratory to the clinic.

Researchers plan to target immune cells responsible for eluding antiretroviral treatment

Certain human immune cells known as macrophages are composed of hybrid HIV strains that elude treatment and antiretroviral drugs, according to a new study by researchers from the University of Florida and other institutions, the Gainesville Sun reports.

Genetic profiling reveals genes active in the earliest brain circuit construction

Long before the brain's neurons can facilitate life's big decisions, they have to find their own destiny in the rapidly developing embryo.

New ultra-sensitive device detects viruses in minutes

Imagine being able to detect in just a few minutes whether someone is infected with a virus. This has now become a reality, thanks to a new ultra-sensitive detector that has been developed by Ostendum, a spin-off company of the University of Twente.

Genomic research lays groundwork for new approaches for treating, preventing skin diseases

The health of our skin - one of the body's first lines of defense against illness and injury - depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface.

New cellular targets for HIV drug development

Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions.

DNA compounds show promise for Lupus

A research team led by a University of Iowa investigator has generated DNA-like compounds that effectively inhibit the cells responsible for systemic lupus erythematosus -- the most common and serious form of lupus. There currently is no cure for this chronic autoimmune condition that damages the skin, joints and internal organs and affects an estimated one million Americans.

Experimental therapy uses immune system to boost cure rate in neuroblastoma

A multicenter research team has announced encouraging results for an experimental therapy using elements of the body's immune system to improve cure rates for children with neuroblastoma, a challenging cancer of the nervous system.

South African Health Minister to launch ‘plan to address mother-to-child HIV transmission’

South African Health Minister Aaron Motsoaledi within the next two weeks is expected to launch a plan to address mother-to-child HIV transmission in an effort to reduce infant mortality in the country, The Times reports.

To spread, skin cancer attacks immune dendritic cells

Dendritic cells are the sentinels of the immune system. When they're alert and on guard, they will marshal the body's immunosoldiers, T cells, to battle at the sight of harmful pathogens. But some diseases, such as cancer, are able to escape their watchful eye. By knocking out or beguiling dendritic cells, they slip the defenses of the immune system and sack the unsuspecting body.

Australian scientist finds two new animal viruses

An Australian scientist has discovered two new animal viruses, one in cattle and the other in mosquitoes - the unknown viruses were found in isolated regions of northern Australia - neither of the viruses cause disease in livestock.
